Substituted for application Serial No. 111,130, August 19, 1949. This application September 10, 1954, Serial No. 455,217

16 Claims. (Cl. 273-121) This invention has as its principal object the provision of governor means, for use with ball-rolling games and the like, including circuits for changing the possible winning combinations of ball objectives or targets, and a governor switch for controlling said circuits, the present application being a substitute for application Serial No. 111,130, filed August 19, 1949, now abandoned.

More detgiled features and objects relate to the provision of governor means of the class described characterized in that it affords a plurality of switches actuated by corresponding cams driven in opposite directions de pendently upon the rotation of a common shaft driven through a differential gearing by separate electromagnetic means and so contrived, by reason of specially selected gear ratios, cam developments, and operating connections for said electromagnetic means, that the turning of the cam shaft in one direction produces a predetermined rate or frequency of change in a positive sense, and in the other direction a possibly different rate in a negative sense, the ultimate object being to actuate the switches in accordance with the frequency of operation of the electromagnetic actuating means at some desired ratio, so that, by way of example, if desired each operation of the electromagnetic means for producing a positive displacement of the cam shaft would produce twice or perhaps only one-half as much turning of the shaft as would operation of the electromagnetic means for producing negative movement.

A further detailed object is the provision of circuit connections for actuating one of the aforesaid electromagnetic dilerential drive means by the score awarding circuits in a known type of ball-rolling game; and to actuate the other electromagnetic drive means by the game starting or operating switch, so that the cam switches are actuated in a positive sense by the starting switch each time the game is played and in a negative sense by the score awarding circuits each time the player scores, in order that control circuits may be set up to increase the possibility of scoring the more often the game is operated without attaining a score, and to decrease the possibilities of scoring as a result of the players successes in scoring, so that the less skillful player is on a more even footing with the skillful player.

Still another aspect of the improvement is the provision, in a game circuit as last above characterized, of switches for changing the odds as well as the winning possibilities in such a game by cutting individual ball switches and groups of said switches into and out of circuit under direct or cooperative control of the novel governor means dependently upon the number of times the game is played and the success or failure of the player in scoring.v

In addition to the foregoing objects, the invention also provides a compact governor unit particularly suited for use in the aforesaid governor circuits and also adaptable to other applications where a differential switch action is required responsive to at least two control factors of variable frequency.

Yet another detailed object is the provisionV in a differlli Patented May 3l, i955 ential switch of the character described of a cam shaft driven in opposite directions through gearing of a differential character, and impulse-operated electromagnetic drive means for actuating Vsaid gearing to produce opposite rotations of the cam shaft different angular amounts responsive to single pulses of equal magnitude and which respectively correspond to opposite (e. g. positive and negative) co-ntrol factors supplied or derived from any source and occurring with the same or different relative frequency.

Additional objects and aspects of the invention pertain to details of the connections, structures, and operation of the illustrative embodiment described hereinafter in view of the annexed drawing in which:

Fig. 8 is a skeletonized perspective of the essential components ofthe governor switch.

One type of ball-rolling game with which the novel circuit governor is used is shown schematically in Fig. l, wherein a conventional playing board 15 is provided with suitable ball operated switches 16 to 2li divided into three groups, A, B, and C. The ball B is launched upon the board by any of several well-known means, such for example as the shooter or plunger 25, to be lodged or skillfully directed against or onto any of the said ball switches.

This type of ball game has a starting switch 26, which may be operated by deposit of a coin, and it has in addition a Free Play Control Means, e. g. a free play switch 27, automatically conditioned as a result of winning a certain score (as by operation of certain winning ball switches) so that the player may continue to play the game without deposit of coins if he achieves a proper score.

Free Play Control Means are known in the art, and one suitable type is described in U. S. Patent No. Re. 20,698 to William H. Bellah.

In order to add interest and variety to this game, the present invention provides an automatic governing means acting to connect the various ball objectives or target switches variously in and out of circuit at different times with the winning register and free play control, and to do so in some predetermined ratio or dependence related to the frequency with which the game is operated and the frequency with which winning combinations or scores are achieved.

Accordingly, the novel governor circuit includes a shaft 28 (Fig. l) driven through a differential gearing generally designated at 29 and 3i).

Fixed upon the governor shaft 23 are a plurality of switch cams numbered 31 through 36, each of which actuates an associated governor switch SEA 36A.

Some of the governor switches (e. g. 35A, 36A) are connected in control circuits with certain ball switches to condition the same to v/in, that is, to render the associated bal-l switch alive for scoring purposes at different times, while others of the governor switches are connested in odds circuits which increase or decrease the number of possible winning switches at a given time or in a given group on the ball playing field. Mechanism is provided, preferably, to indicate to the player which switches are conditioned for scoring, but to simplify the circuit illustrated these features are omitted.

The frequency or order of addition or subtraction of winning or scoring objectives is intended to be a function of the frequency of operation of the game and the number of winning scores achieved by one or another player.

Thus the achievement of a winning score in the game is automatically rendered easy or dicult at different times, and in general, the more the game is played without scoring a free play the greater the possibilities become for achieving such a score; but the facility for scoring a free play is also reduced in a desired ratio to the frequency of winning.

1For illustrative purposes, the differential gearing designated at 29 may be considered the positive or additive governing factor, and this is so controlled as to advance the shaft 28 in a positive direction each time the game starting or conditioning switch 26 is actuated.

This is accomplished by electromagnetic ratchet means 37 t add) connected by conductor 39 to be energized latter unit may be of the type shown in U. S. Patent 2,281,262 to Charles T. Breitenstein, and includes a stepup ratchet pawl 43 actuated by the coil 42 to advance the free play register disc de from a zero or starting position so that pin 45 moves away from switch 46 to permit the latter to close the free play circuit and thereby render the free play control or switch 27 eifective for free operation of the game so long as switch 46 remains closed, it being well understood in the art that each time a free play is taken off by the player (by closing switch 27) the free play award unit steps back once (by step-back means not shown) toward zero position. Thus, if a player is awarded four free plays, the coil and pawl means 482-43 will step the disc (and hence the switch pin 45) four steps away from zero so that it will require four reverse steps (corresponding to taking off four free plays) back to zero before switch 45 is opened again to disable the free play switch.

ln the governor' circuit shown, each time the free play step-up coil d2 is energized the negative or subtracting governor coil 4l-il is energized to impart a subtracting motion to shaft 28.

EXAMPLE I As one example of the governor action in adjusting the win7 frequency, it will be observed that a score relay coil Sti is connected in an operating circuit by conductor 51, governor switch 36A, and conductor 51A to the wiper contact 51B of a rotary win switch having groups of contacts, e` 'g. 52A, 53A, 54B, 54C, etc., variously connected to groups A, B, C, of ball switches i6 to 24.

In the example illustrated in Fig. l the contacts 52A are connected by conductor 52X to one terminal of ball switch 1S in group A.

Under these conditions, if a ball scores by closing switch 18, a circuit is closed via conductor SZZ to a contact 60 on the odds and since at this time the odds switch wiper 60A happens to be on this contact and governor switch 32A is assumed to be closed, a

circuit is completed from odds wiper 60A, conductor 60B, switch 32A to power (plus), thereby energizing the score relay coil 50 via the win stepping switchparticularly one of its contacts 52A, wiper 51B assumed to be in dotted line position, conductor 51A, governor switch 36A, assumed closed, and conductor 5l to relay coil 50, which results in closure of relay contacts 50A (to energize the clutch coil in the pulse multiplier unit), and energization via conductor 41 and wiper 41D of the score register or free play coil 42, resulting in turn in the stepping of disc 44 clockwise to move pin 45 away from the zero-open free play switch 46, so that the latter closes, conditioning the game, say, for four free plays, with other results to be described.

In the illustrative embodiment the number of free plays awarded depends upon how long the clutch in the pulse multiplier remains operated, and hence how far the contact MD travels, and also whether switch 38A is open or closed. If closed, the bank of contacts 41C with six pulsing contacts is operative to pulse coil 42 each time contact 41D sweeps over a contact 41C, while the four contacts 4lB afford additional pulses. lf switch 38A is open then contacts 41C are dead, but the four contacts 41B remain alive and free play coil 42 can be pulsed four times therefrom.

The free play award switch 46, now closed, connects operating power to conductor '70, so that if the free play button switch 27 is pushed contacts 71 close to apply power to conductor 73 and actuate the conventional game reset and ball release unit to condition the game for another round of play.

ln the present embodiment the game is intended to be played with one ball; whether or not the played ball scores, any of the several contrivances well-known in the art returns it ultimately to position before the shooter or plunger 25 as a result of operation of the game reset and ball release unit.

At this juncture a further result of closing the free play switch 27 is noted: contacts 72 also close, applying power to conductor 39 and the governor add coil 37 (provided the governor switch 72X is closed), which causes governor shaft 28 to be turned with a possible actuation of one of the governor switches 3lA-36A.

Still another important occurrence should be noted in the foregoing example: When the score relay means 5t), 50A was actuated, not only was the award coil 42 energized, but the governor subtract coil in? was also energized, resulting in a negative rotation of the governor shaft 28.

Now, since the diiferential gear means 294i) is calculated to turn the shaft different amounts in opposite direc tions according to a predetermined ratio, and since the score values of the various ball switches are different, the aforesaid closure of ball switch l in group A can be presumed to result in applying, for example, four score pulses (through the pulse multiplier, so designated) to conductor 41, resulting in four steps of the free play indicator dial 44, and four pulses to the governor subtract coil 40.

Yet, when the player takes oit a free play by switch 27 (the conventional take-off coil and circuit is not shown) and pulses the conductor 39, and hence the add coil 37 only once, the net result, so far as rotation of the governor shaft 28 is concerned, may be to rotate the governor cams a lesser amount in a positive direction than they were displaced in a negative direction by the preceding award of four free plays, with the ultimate result that the possibility of scoring free plays becomes less likely by reason of the successful free-play score which the player has achieved.

Assume, further, that the ball switch i8, which the player has succeeded in hitting in the latter example, were assigned a value of 1G free plays and, accordingly, the pulse multiplier were adjusted to pulse the conductor 41 and Subtract coil 40 ten times instead of only four,

then the negative or subtractivev action of the governor switch would be considerably in excess of any additive action resulting from operation of either the free play switch 27 or the regular starting or coin switch 26.

It will be appreciated that the ratios involved in the ditferential gearing 29-39 may be selected to produce a wide range of possibilities in governing the negative and positive turning of the shaft 2S different amounts in relation to the actuating or control pulses, whether the latter result from scoring or from the number of times the game is started or played, either by a coin or token or the free starting means.

Odds Control By way of illustrative example, attention is called to the fact (Fig. l) that in the foregoing example, each of the group A ball switches 16, 17, 18, is connected to a contact 60, 61, or 62 on the odds switch, and the odds Wiper 69A is at this time engaged with each of said contacts, so that the latter are in a power circuit (governor switch 32A being closed) with the score relay through the win contacts 52A, and governor switch 36A closed, the win wiper 51B being assumed in the dotted line position.

Thus, a ball approaching the group A targets has three times the opportunityy of scoring that it would have if the odds wiper rested only on the contact 60.

However, if the odds switch were in the described condition, but the win switch were in the full-line position, none of the group A ball switches would be in circuit and no Free Play score could be made at all by hitting any of the targets 16, 17, 18.

Moreover, if either of the governor switches 32A or 3er-i were open in the foregoing examples the scoring would not be the same; if switch 32A were open, there would be no Score Award in Group A; if switches 35A and 36A were open, there would be no Free Play Award.

EXAMPLE Il Assuming the full-line condition of the parts in Fig. l, it is now understood that a ball lodged against any of the Group A targets could not score.

But suppose the ball to engage ball switch 23 in Group C, a score will be awarded only if the governor switches 34A and 35A are closed; this being assumed, an award circuit is completed for score relay coil 50 via conductor 51, governor switch 35A,l conductor 35B, Win wiper contact 35C,l contacts 53C, conductor 53X, ball switch contacts 23, odds contact 35D, odds wiper 35E, and governor switch 34A.

Moreover, under the foregoing conditions, the ball, if played into the Group C objectives, could score Free Plays on either ball switch 22 or 23, but the position of the win switch wiper 35C (as well as odds wiper 35E) eliminates ball switch 24 at this time.

The position of the odds and win switch wipers is varied by means of a motor-driven slip-clutch scrambling drive unit, so designated, turning the switch wipers through an intermittently driven shaft means 69, which changes the positions of said switch wipers without regard to score or playing frequency factors.

It will now be apparent by inspection of Fig. l, that in the full-line condition of the parts, the Group A ball switches are dead` because the win control switch eliminatesthern from the scoring circuit, although the odds control would have rendered one of these Group A switches effective had the win wiper 51B been on contacts 52A, for example.

Conversely, some of the Group B ball switches (i. e. 2G, 21) are conditioned by the win switch to score, but not one of the Group B switches is included in the score circuit by the odds switch.

Accordingly, it is believed that the illustrative circuit connections of Fig, 1 as described reveal the possibilities for a multitude of arrangements for changing the scoring connections sov that different ball switches, or groups S thereof, as well as different numbers of said switches in different groups, may be rendered effective or ineffective at different times by the action of the odds and win switches under control of the governor means, which may or may not be correlated in operation with the scrambling means.

In the example shown, it is preferred that the slip clutch operating coil '75 for the slip clutch means 74 which interconnects the drive motor with the odds7 and win wiper shafting 69, shall be governed by the cam switch 31A, while the scrambling motor is controlled by the game reset unit (as indicated by the dash-dot arrow), the latter causing the motor to run whenever the game is reset, and the governor determining when the clutch 74 is to be operated. lf desired, the scrambling control may be independent of the governor as by having switch 31A controlled by the game reset unit instead of cam 31.

ln practice, there are generally more ball switches than shown in Fig. l, and the odds" and win circuits are connected to have a greater scope of permutation and combination than shown, the illustrative circuits having been simplified to the utmost for demonstration of the principle of the invention and the manner and means by which it is to be practiced.

For purposes of making it relatively easy or difficult to score, the possibilities open to the player may be varied either in the number of ball switches rendered effective in the various groups, or in the number of score points or values to be awarded for any particular ball switch or group of ball switches.

EXAM PLE Il l The foregoing two examples involved mainly a change in the positions of the Scoring switches and the ball-switch connections set up thereby.

However, the contacts on the score award pulse multiplier unit, so designated in Fig. l, may be connected by governor switch 38A, when closed, to increase the number of pulses, resulting from closure of the score relay Se), it being noted that there are four contacts 41B on the multiplier switch, which are normally effective (connected to power as indicated); but closure of governor switch 38A applies power to another group of six contacts 41C, so that the pulse wiper 41D, upon each cycle of travel, may yield four or ten score pulses under control of the governor switch. The actual range of score pulse values afforded in practice is much greater than in the foregoing simple example.

Governor switch unit The governor switch is constructed as a compact unit, as will appear from the top plan view in Fig. 3 wherein the structure is seen to include a pair of frame plates 99 and 91 secured in spaced relation by means of spacers 92, plate having an offset mounting flange 90A. Brackets 93 and 94 are bolted to plate 91 to serve as mounts for the several snap switches 132A 136A, which ride the corresponding cam discs 132 136 fast on the governor shaft 12S, the relative positions of the cams and switches beinU illustrated in Fig. 4.

Referring still to Fig. 3, it will be observed that the differential gear unit generally indicated at 95 is disposed between the mounting plates, and as shown in the detail of Fig. 7, consists of bevel gears 96 and 97 meshing with a pair of planetary pinions 9S carried on stub shafts fixed on the governor shaft 12S. The bevel gear 96 is driven (Figs. 5 and 8) from stub shaft 96E through a train of gears 96A, 96B, 96C, 96D; whereas the other bevel gear 97 and its companion gear 97A are similarly driven through intermediates 97B from drive pinion 97C on stub Shaft 97D.

The gear ratios for the gears associated with the differential gears 96, 97 are not the same, so that for equal displacements of the stub shafts 96E and 97D the rotation of shaft 128 will be different.

As seen in Fig. 2, the stub shaft 96E is driven by the 7 ratchet gear 129 fast thereon, while the other stub shaft 97D is driven by ratchet gear 130, there being separate electromagnets 137 and 14) mounted on the plate 99 with corresponding pawl means 137A, 140A for stepping said ratchets to produce the aforesaid opposite rotative movements of the governor shaft, each ratchet having a corresponding holding pawl 129A, 139A to prevent retrograde movement.

The operation of the governor may be understood from the skeletonized View of Fig. 8 in which the electromagnet 137 may be energized from a circuit such as described for the add coil 37 of Fig. l thereby moving the ratchet gear 129 one step for each impulse to the coil, the resulting motion of stub shaft 96E being transmitted through pinions 96C, 96D, and the intermediate gearing 96B to gear 96A and its bevel gear 96, with a resultant displacement of the planetary pinions 9S, which are carried for planetary rotation on the governor shaft 128.

Impulsing of the electromagnet 140 produces a similar step-by-step movement of the stub shaft 97D, which motion is transmitted through the gearing 97C, 97B, 97A to the differential bevel gear 97, resulting in a reverse movement of shaft 128 from that produced by actuation of coil 137.

The gear ratios mentioned heretofore, as well as the mathematical development or evolution of the several cams 132 136 and angular locating thereof will produce the desired operations at different times responsive to rotation of the governor shaft, said operations being averaged on computed frequency tables based upon a desired or predicted frequency of operation of the drive means or electromagnets 137 and 140, depending upon the desired performance required of the unit and which will form the basis for the selection of said ratios and cam characteristics.

It is contemplated that the invention shall not be limited to any precise details of structure, arrangement, operation or circuit plan or connection, excepting as may be specifically required by the appended claims.
